David Teigland aee27dc7ba scan: skip device rescan in vg_read ... For reporting commands (pvs,vgs,lvs,pvdisplay,vgdisplay,lvdisplay) we do not need to repeat the label scan of devices in vg_read if they all had matching metadata in the initial label scan. The data read by label scan can just be reused for the vg_read. This cuts the amount of device i/o in half, from two reads of each device to one. We have to be careful to avoid repairing the VG if we've skipped rescanning. (The VG repair code is very poor, and will be redone soon.)		2018-04-20 11:23:14 -05:00
